Firstly, the structure of the inner jacket box 4 is that the inner jacket box 4 is a rectangular column formed by sequentially connecting a first surface 41, a second surface 42, a third surface 43 and a fourth surface 44 end to end, the first surface 41, the second surface 42, the third surface 43 and the fourth surface 44 are all provided with a compressed air pipe 2, a row pipe 3 connected with the compressed air pipe 2 and extending towards the inner side of the inner jacket box 4, and an electric control valve 1 arranged on the compressed air pipe 2, wherein the electric control valve 1 is opened, the compressed air pipe 2 enters the row pipe 3 under the pressure of a compressed air source at the rear part, and the inner jacket box 4 is blown out from the row pipe 3 to form an air flow to blow the materials in the inner jacket box 4. The air flow can be generated on all four surfaces, i.e., the first surface 41, the second surface 42, the third surface 43, and the fourth surface 44 of the inner jacket 4, and the air flow blown out from the tubes 3 and reaching the inner jacket 4 is blown out perpendicularly to the wall of the inner jacket 4, that is, the air flow blown out from the first surface 41 is blown out perpendicularly to the first surface 41 toward the third surface 43.
